Norepinephrine :

(1) Is released by sympathetic fibres

(2) Is released by parasympathetic fibres

(3) Increases the heart rate

(4) Decreases blood pressure

Which of the above said statements are correct?

(1) and (4)
(1) and (3)
(2) and (3)
(2) and (4)

Solution

Norepinephrine is released by sympathetic fibres i.e,rapidly secreted in response to stress of any kind and during emergency situations. It increases the heart beat,the strength of heart contraction and the rate of respiration.

Which of the following represents the action of insulin?

Increases blood glucose levels by hydrolysis of glycogen
Increases blood glucose levels by stimulating glucagon production
Decreases blood glucose levels of forming glycogen
Increases blood glucose level by promoting cellular uptake of glucose

Solution

Insulin is a peptide hormone, which plays a major role in the regulation of glucose homeostasis. Insulin acts mainly on hepatocytes and adipocytes (cells of adipose tissue), and enhances cellular glucose uptake and utilization. Insulin also stimulates conversion of glucose to glycogen(glycogenesis) in the target cells.

Select the answer which correctly matches the endocrine gland with the hormone it secrets and its function/deficiency symptom:

Endocrine gland Hormone Function/deficiency symptom

Posterior pituitary Growth Hormone(GH) Oversecretion Stimulates abnormal growth
Endocrine gland Hormone Function/deficiency symptom

Thyroid gland Thyroxine Lack of iodine in diet results in goitre
Endocrine gland Hormone Function/deficiency symptom

Corpus luteum Testosterone Stimulates spermatohenesis
Endocrine gland Hormone Function/deficiency symptom

Anterior pituitary Oxytocin Stimulates uterus contraction during child birth

Endocrine gland	Hormone	Function/deficiency symptom
Posterior pituitary	Growth Hormone(GH)	Oversecretion Stimulates abnormal growth

Endocrine gland	Hormone	Function/deficiency symptom
Thyroid gland	Thyroxine	Lack of iodine in diet results in goitre

Endocrine gland	Hormone	Function/deficiency symptom
Corpus luteum	Testosterone	Stimulates spermatohenesis

Endocrine gland	Hormone	Function/deficiency symptom
Anterior pituitary	Oxytocin	Stimulates uterus contraction during child birth

Solution

• Growth hormone secreted by Anterior pituitary

• Corpus leutum secreted Progesterone

• Oxytocin is secreted by Posterior pituitary
